REINFORCED LOAD BEARING STRUCTUH,
Field of the Invention
This invention relates to a reinforced load bearing stmcttire and morβparticulaily to a concrete load bearing structural member and/or slab with a hollow passageway extending through the structural member or slab.
modem buildings, For example, horizontal slabs of steel reinforced concretetypically between 10 and 50 centimeters thick ate frequently used to construct doors for buildings, Ia many industrial buildings, a thick concrete slab supported on a foundation is used, to construct Hie ground floor of a building.
raαefcrougϊi are also kπom For example, a U.S. PatentNo.2,938,255 discloses a m&tfcod for manufacturing beams with longitudinal passages to reduce weight A more tecent apparatus to provide hollow reinforced concrete floors is disclosed in a U.S. Patent of Breuning, No.5396,747. The Braining disclosure utilizes a planar hollow reinforced? concrete floor slab with "two dimensional structure" to obtain higher streng&and stafiEness* less volume of materials, and to obtain a balance between bending forces, shear forces and deformations and reduce the amount of cement.
A more recent concrete floor system and method of making floor components is describedin aU.S. Patent No.7,024,831 ofCϊarketal. As disclosed taan, me concrete øw concrete blocks for reducing weight and receiving a tension cable therethrough. Opposite ends ø* ifce cable are held on end plates inside recessed ends of each hollow beam. The ends of tfce beams are adapted for mounting next to the inside of the sides of a foundation walL Atop portion of each parallel beam is adaptive to receive a plurality of angularly shaped floor panels. The floor panels interlock next to the top portion of me beam. Notwithstanding the above, it ispjesentty believed that mere is a need and a potential
with the ptesent invention. There should be a potential matoforsuehstrøctuϊesbecaϊJS&ffø volume of the hollow portions can be tailored for specific appfoations by using different shapes and materials such as Styrofoam, P.V.C. pipes and steel pipes. For example, the type and shape of materials varies depending on load, span and depth of a beam. In a case whefe the beam depth is restricted it may be apprøpriate to tise steel pipes or t<*es to incjteasetite carrying capacity of a beam.
The improved reMorced load bearing struciΛires iB accordance with the present invention can also be used with the following advantages; reducing the weight of the concrete member due to me hollow area to thereby reduce the flexural movement due to the weight This also means a reduction in cement and steel reinforcement, and increasing the moment of inertia for the member due to the added moment of inertia frame inserted pipe or tube that will lead to a reduction in deflection. The pipe or tube -will carry part of me flexural moment and this depends on the pipe material and thickness. The result of applying this approach Will provide less slag weight, less steel reinforcement and less cost Further, the system in aoc<waance with the present inventi on elhninat^meά^bean^ andmatøitpossibfeto prepare and fix the reinforcement steel on .the pipes before preparing the slabs and mis Will reduce the time and cost for workers.

Each of the inner support members 60 includes a longitudinally extending hollow passage 22 as defined by a hollow PVC pipe. As illustrated tfre support member 60 includes the stractαre of the second embodiment of the invention. To be more specific, each of the support members 60 include a plurality of longitudinally extending reinforcing rods 26» a rectangular shaped ring or stirrup 38 and a hollow passageway 22 defined by a plastic pipe 23. The concrete slab 50 including the floor 52 and support member 60 are fomed ina plastic or wooden mold 65 and rests on a foundation 66 such as a steel girder.
